Object categorization and scene understanding have long been a central goal of computer vision research. Changes in lighting, viewpoint, and pose, as well as intra-class differences, lead to enormous appearance variation, making the problem highly challenging. Inspired by a paradigm for 3D shape representation that traces its root back to the very early contributions in computer, and leveraging the advances in machine learning and image feature representations that have been crucial for 2D pattern recognition in the past decade, recent work suggests that large gains can be made by acknowledging that objects live in a physical, three-dimensional world. Critically, when modeling scenes, objects and their relations in 3D, we must answer several fundamental questions. How can we effectively learn 3D object representations from images or video? What level of supervision is required? How can we infer spatial knowledge of the scene and use it to aid in recognition? How can both depth sensors and RGB data be used to enable more descriptive representations for scenes and objects?

We are soliciting original contributions which can provide both theoretical and experimental insight on this fundamental problem. Specific questions we would like to address include, but are not limited, to:

Object Representation
 How can we find better representations of the 3D geometry of object instances or classes to further improve recognition?
 How can we represent/recognize objects that have variable shape structure?
 How can we use the 3D object representation as building blocks for higher-level tasks, such as scene understanding?
 How can we utilize synthetic 3D training data (CAD models) besides real images and kinect-style depth data to learn better object representations?

Kinect: Combining Depth and RGB Sensors
 How can we represent and recognize object categories using both RGB and depth sensors?
 How can we estimate scene surfaces and physical interactions?
 How can depth and RGB data help extract object functional parts and affordances?

Reconstruction and Recognition
 Can recognition and reconstruction be run simultaneously to enhance each other?
 How much does 3D information help?
 How detailed does the 3D representation need to be in order to achieve satisfactory recognition?
 Blocks world" interpretation seems to be making a return as well. How can we recover such abstract representations from more realistic scenes?

Spatial Inference
 How can we represent and infer the depth and orientation of surfaces and free space in indoor and outdoor scenes?
 How can alternative representations, such as depth maps and surface layout estimates, be combined to improve robustness?

Spatial constraints and contextual recognition
 How can we use/explore different degrees of 3D spatial constraints (e.g. ground plane) for recognition?
 How can 3D spatial constraints be used for joint recognition of scenes and the objects within?
 What's s the relationship between shape models and functional models?

Human vision
 What can we learn from what we know about our own visual system? How do we humans represent 3D objects or the 3D environment? Can this inspire computational work?
